I don't know whether the design on this bag is (a)
instructions not to dispose of cigarettes in the bag, (b) inveighment
against smoking (the KLM parent company bans all smoking on its flights --
and I assume the same is true of its offspring firms), or (c) a subtle new
logo design.

In any case, the designer doesn't seem to be constrained by
practicalities. The instruction "after use fold forward" is
printed diagonally right at the bottom of the bag. If you take this
literally, you'll be OK if all you've done is to spit your chewing gum
into this bag. Otherwise, you'll tip the entire contents onto your lap. I
recommend calling the cabin crew before doing this so they can help you
clear up.

Daniel Kahleyss says this
bag is from 1994 or 95.
Thanks, Daniel.
